4 Quick Finder Installation procedure (overview) Reading triggering via polling reflector (default setting) 1. Check scope of delivery for completeness. 2. Install the CLV at the reading station and align the reading window with an object possessing a bar code. 3. Align the supplied white polling reflector (special code) to the reading window of the CLV with a reading distance of approx. 300 mm (11.82 in) and fix the reflector temporarily at the side of the reading station. Later, the reflector should be in the center of the scan line (white reflector: distance 40 to 500 mm (1.58 to 19.7 in), blue reflector: distance 500 to 800 mm (19.7 to 31.5 in)) 4. Install the CDB 410 or CDM 410 connection module. 5. Connect the CLV to the CDB 410 or CDM 410 connection module. 6. Connect the host to the "host interface" in the CDB 410 or CDM Switch on the power supply to the CDB 410 or CDM 410. After the CLV has been started, the "Device Ready" LED lights up. The beeper signals that reading mode has been started by means of two consecutive tones. 8. Switch on PC and start Windows TM (at least Windows 95 TM required). 9. Install accompanying user software "CLV Setup" and online help "CLV Setup Help" from CD ROM ( Manuals & Software ) to PC. 10. Connect the PC to the host interface 2 of the CLV. For this purpose, connect the PC via a 3-core RS 232 data cable (null modem cable) to the 9-pin "Aux" plug in the CDB 410 or CDM Start "CLV Setup" user software. CLV Setup starts the communication with the CLV and copies the parameter set of the CLV via an upload. The parameter set is displayed on tabs. 12. Start the terminal emulator in CLV Setup. 13. Carry out a test reading with a bar code pattern in the following sequence: - block the polling reflector, e. g. using a sheet of paper - present the bar code pattern at a reading distance of approx. 200 mm (7.88 in) (not for CLV 414) - unblock the polling reflector If the bar code was read successfully, the reading result is displayed in the terminal emulator. 14. Configure the CLV for the application by means of the setting options on the tabs in CLV Setup. Copy the modified parameter set temporarily to the CLV via download. Do not switch off the power supply of the CDB 410 or CDM 410 (of the CLV)! 15. Run a test under realistic conditions. 16. Check proper data transfer of the CLV to the host. 17. Correct and optimize the set parameter values if necessary. Copy the parameter set to the CLV permanently via download. 18. Save the parameter set as a "*.scl" configuration file in CLV Setup. The CLV contains application-specific settings and is ready for operation. I-4 SICK AG Division Auto Ident Germany All rights reserved /O079/

16 Chapter 2 Safety information 2.3 General safety instructions and protection measures Carefully read the general safety instructions and observe them at all times. This also applies to the warnings provided for the activities described in each chapter of this document. Risk of injury by electrical current In the CDM 410 Connection Module, the optional CMP 400 Power Supply Module is connected to a mains voltage of 100 to 250 V AC/ 50 Hz to 60 Hz. When working with electrical equipment, always follow the relevant safety regulations. Laser radiation can seriously damage your eyesight. The CLV uses a class 2 red-light laser. Looking directly at the laser beam can seriously damage the retina in your eyes. The entire glass window acts as a laser outlet aperture. Caution use of controls or adjustments or performance of procedures other than those specified herein may result in hazardous radiation exposure. As with sunlight, never look directly into the laser beam. Do not direct the laser beam at other persons. Mount and align the CLV in such a way to prevent the laser beam reflecting off mirrored surfaces. Do not open the housing. (Opening the housing does not deactivate the laser diode). Observe the laser protection specifications (latest version). Laser power The laser operates at a wavelength of λ = 670 nm (visible red light). The power output of the laser beam at the reading window is max. 1.2 mw. The emitted beam is not dangerous to human skin. The product is classified in laser class 2 (laser class II) in accordance with EN , IEC , and 21 CFR (for publication date, see the warning sign on the device). Laser warnings The laser warning labels (Fig. 2-1) are attached at the following positions on the CLV: The laser warning symbol and the laser warning in GB English/US English on line/raster scanners are positioned beside the reading window on the wide side of the device (Fig. 3-1, Page 3-5). The additional laser warnings in English applicable to the USA are positioned beside the reading window on the front side of the device and at the back end on the wide side. The laser warning symbol and the laser warning in GB English/US English on line/raster scanners with a 105 angle attachment are positioned beside the reading window on the wide side (Fig. 3-1, Page 3-5). The additional laser warnings in English applicable to the USA are positioned on the back side of the attachment of the device and at the back end on the wide side. 2-2 SICK AG Division Auto Ident Germany All rights reserved /O079/

17 Chapter 2 Safety information black-yellow signed on device: black-silver signed on device: Fig. 2-1: Laser warning labels found on the CLV Note Explanation The device is supplied with an additional set of laser warning labels in German/US English and in French/US English. If necessary, these can be used to cover the GB English/ US English warning. If the CLV is installed in a machine/panel with the result that the laser warning labels are no longer visible, additional warnings (not included in the scope of delivery) must be provided on the machine beside the emergence aperture of the laser beam. Internal protective circuits The CLV is equipped with monitoring circuit-breakers that switch off the laser diode if problems arise with the laser beam. No maintenance required to keep this product in compliance with laser class II. Activation and deactivation of the laser diode when reading is controlled by the reading pulse (trigger source). A timer (laser timeout) automatically deactivates the laser diode 10 minutes (default setting) after a continuous reading pulse is initiated in reading mode with switching input pulse modes "Sensor Input" and "Serial Interface". In this case, the CLV outputs three consecutive tones via the beeper. The reading pulse interval is to be terminated by resetting the pulse signal. The laser diode is activated again by the next reading pulse. The laser timeout can be set in the range of 1 min to 25 h or deactivated (see Table 6-4, Page 6-9). In the "Percentage Evaluation" mode and "AutoSetup" mode as well as in the pulse modes "Free Running" and "Continuous Read", in reading mode, the laser diode is constantly activated. In the "reflector polling" trigger mode the laser diode is switched on for each 20th scan /O079/ SICK AG Division Auto Ident Germany All rights reserved 2-3

18 Chapter 2 Safety information 2.4 Quick stop and quick restart Switching off the CLV Switch off the power supply or remove the CLV connector from the connection module. This can result in loss of the following (at the most): the application-specific parameter set, if it was only stored temporarily in the CLV the last reading result daily operating data (operating hours counter, trigger count, good read count) Restarting the CLV Switch on the supply voltage or reattach the CLV connector to the connection module. The CLV resumes operation with the parameter set that was last stored permanently and resets the daily operating data. 2.5 Environmental information The CLV is designed to cause minimum impact on the environment. It does not contain any silicone-based materials on the housing surface and, therefore, does not represent any problems for e.g. paint sprayers in paint shops Power requirements The power requirements are particularly low: the CLV 410/412/414 scanners have a max. power consumption of 3 W The value is given for devices with disconnected switching outputs Disposal after final decommissioning Always dispose of unusable or irreparable devices in a manner that is not harmful to the environment and in accordance with the applicable national waste disposal regulations. The CLV can be separated into recyclable secondary raw materials and special-category waste (electronic scrap). See Chapter 7.3 Disposal, Page 7-2. At present, SICK AG does not accept any unusable or irreparable devices. 2-4 SICK AG Division Auto Ident Germany All rights reserved /O079/

24 Chapter 3 Product description 3.2 Method of operation The CLV first scans the bar code with a scan line and then decodes it. The CLV forwards the data via the serial host interface to a host/pc for further processing. An overview of the CLV functions is provided in Fig CLV 41x PC Operation Parameterizing, etc. Photoelectric switch Reading pulse HOST Further processing of the reading result Signal Teach-in match code 1 5 to 30 V DC Status indicator e.g. Device Ready e.g. Good Read e.g. No Read Fig. 3-2: Block diagram: CLV functions The tried and tested standard decoder of the CLV series is available for decoding. The CLV derives useful diagnosis data from the reading process and transfers it to the host. It also records operating data that can be interrogated at any time. The quality of the read can be checked in "Percentage Evaluation" mode. To start a reading process when an object is located in the reading field, the CLV requires a suitable trigger. This opens a time window ("reading interval") in the CLV for the reading procedure. In the default setting, this trigger is supplied by the automatic reflector polling. Alternative trigger sources include external reading pulse sensor, free-running mode or a command via the host interface 1 (RS 422/485). The current operating status is indicated by four LEDs. A beeper indicates the status of the reading result. In the default setting, the "Good Read" function is selected for this. If the trigger is supplied externally by a sensor, the "Sensor 1" switching input signals the start of the reading procedure to the CLV. The "Sensor 2" switching input can be used to teach in a match code. The "Result 1" to "Result 3" switching outputs can be assigned various functions and trigger external devices, such as a PLC. The CLV is operated and configured via the host interface 2 (RS 232) using the "CLV Setup" software or via one of the host interfaces and command strings. The CLV can also be configured using profile bar codes. The optional outputting of the error status ST via the host interface helps you with configuration and with locating the source of errors during startup and in reading mode. 3-6 SICK AG Division Auto Ident Germany All rights reserved /O079/

25 Chapter 3 Product description Scan procedure variants Line scanner Generates a scan line. Due to the V-principle of beam deflection, the reading field height (for evaluating the useful length of the scan line) is dependent on the reading distance. Raster scanner Generates 8 parallel scan lines that are offset by the same distance. Due to the V-principle of beam deflection, the reading field height (for evaluating the useful length of the scan lines) is dependent on the reading distance. Raster height of the scan line field: 15 mm (0.59 in) at a reading distance of 200 mm (7.88 in) (front reading window). 3.3 Indicators and operating elements Operating elements The CLV is operated and configured via the host interface 2 using the "CLV Setup" program or using command strings sent to one of the host interfaces. A variety of parameterizing options allow you to adapt the device to a wide range of applications. The following can be defined (among others): the configuration of the code types to be read the reading, evaluation and output characteristics the communication parameters of the host interface the structure of the data output string for "good read" and "no read" on the host interface Chapter 10.3 Installation and operating instructions for the PC-based "CLV Setup" program, Page 10-5 describes the procedure for installing the "CLV Setup" program and how to operate the user interface. Configuration (parameterizing) is explained in Chapter 6.4 Configuration (parameterizing), Page Function of the LED indicators Four LEDs indicate the operating status, activity of the laser diode, output of the reading result, and data transfer on the host interface. The LED indicators (Fig. 3-3) are located on the rear of the device. Table 3-2 shows the meaning of the LED indicators in the different operating modes/functions.

For information on troubleshooting, see Chapter 8.4 Troubleshooting, Page 8-3. In the default setting, the beeper indicates the event status "Good Read" by means of a "Low" (quiet) beep. It is assumed in these operating instructions, that the beeper is operated with the default setting in Reading mode. The sound opening of the beeper is located on the rear, narrow side of the device and below the LED labeling. 3-8 SICK AG Division Auto Ident Germany All rights reserved /O079/

30 Chapter 4 Installation Replacing the laser warning label If necessary, replace the laser warning label in GB English/US English on the CLV with the required language (Fig. 4-1). The device is delivered with a set of laser warnings in: German/US English French/US English See also Chapter 2.3 General safety instructions and protection measures, Page 2-2. Included label set: Fig. 4-1: Example line scanner: replacing the laser warning label Selecting the installation location When you select the installation location, the distance between the CLV and the host and between the CLV and the bar code are important. Distance between the CLV and the host The CLV can be installed without a connection to a bus connection max. 1,200 m (3,936.9 ft) away from the host. The distance which can be achieved depends on the selected type of the host interface and the set data transfer rate, however. See Table 5-2, Page 5-3. Distance between the CLV and the CDB 410 or CDM 410 connection module The CDB 410 or CDM 410 connection module must not be located further than 10 m (32.8 ft) from the CLV, since the "CLV Setup" program on the PC accesses the host interface 2 of the CLV via the module (RS 232) Mounting accessories The CLV is mounted with the help of two tapped blind holes (M4) located on the bottom narrow side of the device. Fig. 4-2 shows the position of the threaded hole for both housing models.

32 Chapter 4 Installation Distance between the CLV and the bar code Basic alignment of the scan line to the bar code Depending on the application, the line scanner or raster scanner version of the CLV is used. Fig. 4-4 shows how the device is aligned with the bar code on the object for each of the two scanning methods. Line scanner Raster scanner Fig. 4-4: Scanning methods: alignment with bar code and conveyor direction Reading distance between bar code and aperture angle α The distance between the reading window of the CLV and the bar code must not exceed the technical limits. The height of the reading field is shown as a function of the reading distance a for various resolutions (module widths) in Chapter 10.2 Specification diagrams, Page Fig. 4-5 shows the definition of the reading distance a from the reading window and of the aperture angle α for each of the two scanning methods. Line scanner Raster scanner Reading distance a Reading distance a Fig. 4-5: Definition of the reading distance a and the aperture angle α For both scanning methods, the useable aperture angle α is max. 60 with front reading window and max. 50 with side reading window (additional 105 angle attachment). Due to the V-principle of beam deflection, the reading field height (for evaluating the useful length of the scan line) depends on the reading distance. 4-4 SICK AG Division Auto Ident Germany All rights reserved /O079/

33 Chapter 4 Installation Angular alignment of the CLV Optimum alignment of the CLV is achieved when the scan line travels over the bar code lines almost at a right angle (90 ) (Fig. 4-4). All possible reading angles that can occur between the scan line and the bar code must be taken into consideration (Fig. 4-6 and Table 4-1). β α Reading area α: Azimuth angle (tilt) β: Inclination angle (pitch) γ: Rotation angle (skew) γ Reading distance Fig. 4-6: Line scanner: reading angles between the scan line and the bar code Angle Azimuth α (tilt) Inclination β (pitch) Skew γ Limit max. 15 (depending on the code print) max. 45 (depending on the module width) max. 45 (depending on the module width) Table 4-1: Permissible reading angles between the scan line and bar code Preventing surface reflection If the light from the scan line strikes the surface of the bar code perpendicularly, interference may be caused by reflections when the returned light is received. To prevent this effect, the CLV must be installed in such a way that the emitted light is tilted slightly with respect to the vertical axis. Fig. 4-7 shows an example of this using the line scanner. Line scanner (front reading window) Line scanner with 105 angle attachment (side reading window) top view top view Fig. 4-7: Preventing surface reflection: angle between the emitted light and bar code (tilted away from the vertical axis) The laser beam from the line/raster scanner with angle attachment is emitted at an angle of 105 with respect to the housing. Depending on the application, the device can also be installed flush with the conveyor belt /O079/ SICK AG Division Auto Ident Germany All rights reserved 4-5

34 Chapter 4 Installation Count direction of the code position CP Explanation The CLV can scan and decode several bar codes with each read. In doing so, it determines the specific local reading diagnosis data for each bar code, i.e. the position (CP value) of the center of the bar code within the scan line. Fig. 4-4 shows the count direction of the code position. By determining the CP value, the device can separate identical bar codes (code type, code length, and data content) and assign the bar code data in the reading result to its position on the object. Line/raster scanner Line/raster scanner with angle attachment 100 CP 100 CP 0 0 Front reading window Side reading window Deflection angle α (aperture angle) in scan direction: 1 = 2 CP (50 = 100 CP) Fig. 4-8: Count direction of the code position CP within the scan line Tip In the default setting, the CLV does not output the value "CP" in the reading result of the host interface. If this is required to evaluate the result in the host, the values can be included in the Separator of the output string using the CLV Setup program. Configuring the Separator: 1. Select the DATA STRINGS tab. 2. Click the SEPARATOR field. The dialog window EDIT PARAMETER: TFS dialog box is displayed. 3. In the drop-down list, click the CP parameter. CP then appears on the top line. 4. Confirm the dialog box with "OK". 5. Perform a download to the CLV. This is done by clicking in the toolbar. The DOWNLOAD PARAMETER dialog box is displayed. 6. Confirm the dialog box by selecting the PERMANENT save option. The CLV outputs the CP value for each bar code in the reading result via the host interface. The values are displayed as a 3-digit number in the associated Separator. 4-6 SICK AG Division Auto Ident Germany All rights reserved /O079/

35 Chapter 4 Installation 4.3 Installing and adjusting the device Installing the CLV 1. Prepare the base for installing the bracket as described in Chapter Laying out accessories, Page Place the object containing the bar code within the visible range of the CLV (in the position at which it is to be read) with the conveyor belt switched off. 3. Align the CLV with the bar code (in accordance with the scanning method) in such a way that with the line/raster scanner, the narrow end with the LED indicators is almost parallel with the bar code surface with the line/raster scanner with angle attachment, the wide side with the laser warning labels is almost parallel with the bar code surface All of the possible reading angles must be taken into consideration. See Fig. 4-6, Page If relevant to the evaluation, pay attention to the count direction of the code position if applicable. See Fig. 4-8, Page Install the CLV bracket on the base. Risk of damage to the device The maximum depth of engagement of the two tapped blind holes M4 is 6 mm (0.24 in). Longer screws will damage the device. Use screws with the correct length. 6. Screw the M4 screws through the bracket into the tapped blind holes of the CLV. 7. Tighten the screws slightly. 8. Adjust the CLV as described below Adjusting the CLV The "percentage evaluation" mode supports the adjustment of the CLV. In this mode, the CLV displays the quality of the bar code reads that enter the CLV reading field statically (the object is not moved on the conveyor belt). The CLV performs 100 scans in Free Running mode and evaluates the reading quality statistically. It outputs the reading result continuously every 2 s via the host interfaces. The behavior of the "Result" LED also indicates the reading quality: LED is extinguished if reading quality is < 30 % LED flashes twice per second if the reading quality is 30 % to 70 % LED flashes five times per second if the reading quality is 70 % to 90 % LED is lit continuously if the reading quality is > 90 % 1. Connect the CLV to the CDB 410 or CDM 410 connection module and switch on the power supply to the module (see Chapter Connecting the power supply, Page 5-5). Once the CLV has started, it outputs a tone to indicate that the self-test was successfully completed. Shortly afterwards, it outputs two tones to indicate that it has assumed Reading mode. The "Device Ready" LED lights up /O079/ SICK AG Division Auto Ident Germany All rights reserved 4-7

36 Chapter 4 Installation 2. Connect the PC to the host interface 2 of the CLV. For this purpose, connect a 3-core RS 232 data cable (null modem cable) to the internal 9-pin "Aux" plug of the module (see Chapter Connecting the PC to the host interface 2 (RS 232), Page 5-7). 3. Start Windows and "CLV Setup" on your PC (see Chapter Starting "CLV Setup", Page 10-8). Activating Percentage Evaluation mode: 4. From the VIEW menu, choose PERCENTAGE EVALUATION. The Terminal Emulator is launched and displays the reading result continuously (see Chapter Percentage evaluation, Page 6-17). Monitor the reading quality (%) during each of the subsequent steps! Performing fine adjustment: 5. Align the CLV in such a way that the angle between the scan line and the bars on the bar code CLV is almost To prevent interfering reflections, tilt the CLV away from the vertical axis so that the light strikes the bar code at an angle of approx. 105 (line scanner) (Fig. 4-7, Page 4-5). 7. If necessary, position the center of the red scan line exactly on the bar code (see Chapter 4.4 Installing external components, Page 4-8). 8. Move objects carrying bar codes into the CLV reading field manually under realistic conditions and check the reading result. If the objects are aligned randomly, or if the bar code is located at different positions (angles), ensure that the limit values of the permissible reading angles are not exceeded. 9. Adjust the CLV in such a way that the good read rate is between 70 and 100 %. 10. Tighten the screws on the CLV. The CLV is aligned with the bar code. 4.4 Installing external components Installing the CDB 410 or CDM 410 connection module 1. Install the CDB 410 or CDM 410 connection module near the CLV. The distance between the connection module and CLV must not exceed 10 m (32.8 ft). 2. Install the CDB 410 or CDM 410 in such a way that the device can be accessed when opened. The host interface 2 (RS 232) of the CLV is accessed via the internal 9-pin "Aux" connector. Detailed information on the installation and electrical installation procedures is provided in the CDB 410 Connection Module (order no , German/English version) respectively in the CDM 410 Connection Module Operating Instructions (order no , German/English version) Installing the polling reflector The reading pulse can also be triggered by the presence of an object in the reading field, independent of an external reading pulse sensor, by using the "Reflector Polling" pulse mode of the CLV. In order to do so, attach one of the two polling reflectors (special bar codes) included with the device opposite the CLV behind the conveyor belt (Fig. 4-9). Table 4-2 lists the permissible range values for the polling reflectors. The pulse type is selected in the default setting. 4-8 SICK AG Division Auto Ident Germany All rights reserved /O079/

37 Chapter 4 Installation Polling reflector white blue mm = 1.97 in / 144 mm = 5.67 in Fig. 4-9: Line scanner: installation location of the polling reflector Device type Reflector Range (scanning frequency 500 Hz) CLV 410 white blue 40 to 500 mm (1.58 to 19.7 in) 500 to 800 mm (19.7 to 31.5 in) CLV 412 blue 150 to 350 mm (5.9 to 13.8 in) CLV 414 blue 230 to 650 mm (9 to 24.4 in) Table 4-2: Permissible range values for the polling reflectors Explanation Note When reflector polling is used, the CLV activates the laser diode with every 20th scan and checks whether it detects the reflector. If the reflector is visible, the CLV repeats the procedure after the next 20 scans. If the reflector is concealed by an object entering the reading field, the CLV starts the reading pulse. This pulse ends when the CLV detects the reflector again. Following this, the CLV repeats the above procedure. When the CLV is switched on, the polling reflector must be visible before the first reading pulse can start. The CLV does not output the data content of the polling reflector in "Reading" mode. This pulse mode is not suitable for applications where time is critical. The max. delay between the reliable detection of the reflector and the start of the internal reading interval is approx. 100 ms at a scanning rate of 200 Hz. Adjusting the polling reflector roughly: 1. Connect the CLV to the CDB 410 or CDM 410 connection module and switch on the power supply to the module (see Chapter Connecting the power supply, Page 5-5). Once the CLV has started, it outputs a tone to indicate that the self-test was successfully completed. Shortly afterwards, it outputs two tones consecutively to indicate that it has assumed Reading mode. The "Device Ready" LED lights up. 2. Align the CLV optimally with the bar code on the object (see Chapter Adjusting the CLV, Page 4-7). 3. Choose a suitable polling reflector for the device type, as shown in Table 4-2. Other ranges available on request. 4. Secure the polling reflector directly opposite the CLV on a suitable base (movable bracket, wall) temporarily so that the CLV has an unobstructed view of the reflector in the gaps between the objects and can scan them reliably. The reflector must be in the center of the scan line, see Fig /O079/ SICK AG Division Auto Ident Germany All rights reserved 4-9

38 Chapter 4 Installation Activating Percentage Evaluation mode: 5. From the VIEW menu, choose PERCENTAGE EVALUATION. The Terminal Emulator is launched and displays the reading result continuously (see Chapter Percentage evaluation, Page 6-17). Fine-adjusting and securing the polling reflector: 6. Align the reflector with the CLV (not vice versa!) until a good read rate of 95 to 100 % is reached. In doing so, prevent any surface reflection (see Chapter Distance between the CLV and the bar code, Page 4-4). The CLV outputs the data content of the unconcealed polling reflector with the identifier "REPO". 7. Once the device is in the final attachment position, remove the protective film from the rear of the reflector and stick it to the base. 8. Check whether the device operates correctly with objects moving under realistic conditions on the conveyor belt. Readjust the reflector if necessary. Activating Reflector Polling pulse mode in the CLV (N/A with default setting): 1. Select the DEVICE CONFIGURATION tab. 2. Click the READING TRIGGER PARAMETERS button. The READING TRIGGER PARAMETERS dialog window is displayed. 3. Activate the REFLECTOR POLLING option in the READING TRIGGER SOURCE section. 4. Confirm the dialog box with "OK". 5. Perform a download to the CLV. This is done by clicking in the toolbar. The DOWNLOAD PARAMETER dialog window is displayed. 6. Confirm the dialog window by selecting the PERMANENT save option. The CLV is then operating in the "reflector polling" pulse mode Alternative: Installing the external reading pulse sensor If the CLV is triggered by an external reading pulse sensor, the sensor must be mounted in the vicinity of the CLV and be connected to the "sensor 1" switching input. The pulse type is not selected in the default setting. Fig shows two examples of where a photoelectric reflex switch can be installed. This depends on the distance a from the bar code to the front edge of the object. Depending on the application, you may need to attach the sensor in such a way that bar codes on objects of different sizes can be read completely during the reading interval. Bar code in the middle or at the end of the moved object a Bar code at the beginning of the moved object a b b < a b b < a Fig. 4-10: Line scanner: installation example for the external reading pulse sensor 4-10 SICK AG Division Auto Ident Germany All rights reserved /O079/

39 Chapter 4 Installation 1. Attach the reading pulse sensor to the installation location. 2. Connect the reading pulse sensor to the "Sensor 1" switching input of the CLV via the CDB 410 or CDM 410 connection module (see Chapter Connecting the "Sensor 1" switching input, Page 5-10). 3. Connect the CLV to the CDB 410 or CDM 410 connection module and switch on the power supply to the module (see Chapter Connecting the power supply, Page 5-5). After the CLV has started, it emits a tone to indicate that the self-test was successful. After a short while, it outputs two consecutive tones to indicate that it has switched to Reading mode. The "Device Ready" LED lights up. 4. Connect the PC to the host interface 2 of the CLV. For this purpose, connect a 3-core RS 232 data cable (null modem cable) to the internal 9-pin "Aux" plug of the module. (See Chapter Connecting the PC to the host interface 2 (RS 232), Page 5-7.) 5. Start Windows and "CLV Setup" on your PC (see Chapter Starting "CLV Setup", Page 10-8). Parameterizing an external sensor as a trigger source: 6. Select the DEVICE CONFIGURATION tab. 7. Click the READING TRIGGER PARAMETERS button. The READING TRIGGER PARAMETERS dialog window is then displayed. 8. Choose SENSOR INPUT (ACTIVE HIGH) in the READING TRIGGER SOURCE section and activate the dialog box. 9. Perform a download to the CLV. This is done by clicking in the toolbar. The DOWNLOAD PARAMETER dialog window is displayed. 10. Confirm the dialog window by selecting the PERMANENT save option. The CLV operates with the "Sensor 1" switching input as an external trigger source. The reading pulse starts when power is applied. Carrying out a test reading: 11. From the VIEW menu, choose READING MODE. The Terminal Emulator window is then displayed. The CLV is in Reading mode. Monitor the reading result during each of the subsequent steps! 12. Move objects with bar codes into the CLV reading field manually under realistic conditions. 13. Check whether the reading result and trigger pulse are correct. 14.

43 Chapter 5 Electrical connection 5.4 Preparations for electrical connection Requirements for the host interface The host interfaces of the CLV can be operated as RS 422/485 or RS 232 interface. Table 5-2 shows the recommended maximum cable lengths as a function of the selected data transfer rate. Note Interface type Transfer rate Distance from host RS 232 up to 19,200 bd max. 10 m (32.8.ft) 38,400 to 57,600 bd max. 3 m (9.84 ft) RS 422/485 1) max. 38,400 bd max. 1,200 m (3,937 ft) max. 57,600 bd max. 500 m (1,640 ft) 1) with suitable line termination according to specification Table 5-2: Maximum cable lengths between the CLV and host To prevent interference, do not lay the cable parallel with power supply and motor cables over long distances, e.g. in cable ducts. To meet the FCC-regulations, the cables have to shielded including connections from shielding to the connector casings Power supply Note The CLV requires a power supply of 5 to 30 V DC (functional extra-low voltage) in accordance with the standard IEC The functional extra-low voltage can be generated by using a safety isolating transformer pursuant to IEC 742. The CLV has a power consumption of max. 3 W (when switching outputs are not connected). The CLV is supplied with 6 to 30 V DC via the CDB 410 or CDM 410 connection module. If the CMP 400 Power Supply Module is used in the CDM 410, a mains voltage of 100 to 250 V AC/50 to 60 Hz is required. The CLV 41x is UL certificated when a class 2 power supply according to UL 1310 is used. Power-up delay The selected device number (default setting: 1) affects the power-up delay of the device. This is useful if a large number of CLVs (e.g. in the SICK Network) are supplied from one power source. Table 5-3 contains a list of the available intervals.

44 Chapter 5 Electrical connection Non-SICK power pack/connections without the SICK connection module Note If a non-sick power supply unit is used instead of the CDB 410 or CDM 410, it must provide a functional extra-low voltage in accordance with the standard IEC and a continuous power output of at least 4 W. The output circuit must be reliably electrically isolated from the input circuit. Do do so, use a safety isolating transformer pursuant to IEC 742. The minimum wire cross-section for the power supply (pin 1/pin 5) is 0.15 mm 2 (approx. 26 AWG). Use the cable no with 15-pin D Sub HD socket and open wire ends to connect the CLV. The color assignment of the wires is shown in Table 5-4, Page 5-4. The CLV 41x is UL certificated when a class 2 power supply according to UL 1310 is used.

45 Chapter 5 Electrical connection Connecting the power supply If the CLV is powered via the CDB 410 or CDM 410 connection module, the power supply does not have to be wired separately. 1. Ensure that the power supply to the connection module is switched off. 2. Connect the 15-pin plug on the CLV to the corresponding socket on the CDB 410 or CDM 410 and screw it tightly. The connection cable can be extended by 2 m (6.56 ft) using the extension cable no The data and function interfaces of the CLV are connected to the connection module. or External power pack: Connect the power supply to the red wire (pin 1, +V S ) and the black wire (pin 5, GND) of cable no (See also Table 5-4.) Connecting the host interface The CLV provides two host interfaces in the combination RS 422/485 (interface 1) and RS 232 (interface 2), Fig Both interfaces operate parallel using identical communication parameters. One of the interfaces must be selected for permanent data communication with the host. If the RS 232 interface is not connected to the host, it can be used exclusively (e.g. with a PC) to monitor data traffic on the parallel RS 422/482 interface. The CLV is configured via the interface 2 by temporarily connecting a PC (see Chapter Connecting the PC to the host interface 2 (RS 232), Page 5-7).

46 Chapter 5 Electrical connection Risk of damage to the interface module Electronic components in the CLV may be damaged if the host interface is connected incorrectly. Connect the host interface as shown in Fig Check the connections carefully before you switch on the CLV. Connect the host interface on the CLV to the host using shielded cables (EMC requirements). Ensure that the maximum cable lengths are not exceeded (Table 5-2, Page 5-3). In the default setting, the CLV communicates with the host via the host interface using the values shown in Table 5-5, Page 5-6. Parameter Value Interface model host interface 1: RS 422/485 host interface 2: RS 232 Data transfer rate 9,600 bd Data bits 8 Parity none Stop bits 1 Protocol SICK (start character: STX, stop character: ETX, no request for repeat: none, timeout: 50 ms) Table 5-5: Communication parameters for the host interfaces (default setting) TIP The communication parameters can be changed, if necessary, on the HOST INTERFACE tab. To do so, change the values under DATA FORMAT and INTERFACE PROTOCOL. Temporarily activating the default setting of the communication parameters: Reading the profile bar codes no. 11 (see Chapter 10.4 Configuring the CLV with profile bar codes, Page ), the CLV resets temporarily the parameters to the default setting described above if the communication parameters are different. This enables the communication with the PC only via the host interface 2 (RS 232). Reading the profile bar codes no. 12 the CLV returns to the current communication parameters. When starting the communication with the CLV, CLV Setup resets automatically the parameters in the CLV temporarily to the default setting. For connecting the host interface via the CDB 410 or CDM 410 Connection Module, see the CDB 410 Connection Module (order no , German/ English version) respectively the CDM 410 Connection Module (order no , German/English version). Terminating the RS 422 interface The interface can be terminated in the CDB 410 or CDM 410 connection module.

47 Chapter 5 Electrical connection Connecting the PC to the host interface 2 (RS 232) The CLV is operated and configured with the"clv Setup" program. In order to do so, you must temporarily connect the device to the PC via the host interface 2 (RS 232). Temporarily disconnect any existing electrical connection between the host interface 2 and the host! We also recommended disconnecting any existing connection between the host interface 1 (RS 422/485) and the host to avoid interferences while parameterizing the CLV. Set the communication parameters of the host interface 2 temporarily according to Table 5-5 using CLV Setup. When starting the communication with the CLV, CLV Setup automatically resets the communication parameters in the CLV after a query (see Fig. 10-5, Page 10-9). You can connect the PC to the CLV in two ways, the cable length must not exceed 10 m (32.8 ft): 1. Connecting the PC to the Aux plug in CDB 410 or CDM 410 connection module Fig. 5-2, Page 5-5 shows the connection diagram of the host interface 2. For connecting the host interface 2 (RS 232) via the CDB 410 or CDM 410 Connection Module as well as setting the required switches and jumpers, see the CDB 410 Connection Module (order no , German/ English version) respectively the CDM 410 Connection Module (order no , German/English version). 1. Switch off the PC and power supply to the SICK connection module. 2. Connect the PC to the internal, 9-pin "Aux" plug of the connection module. Use a 3-core RS 232 data cable (null modem cable) for this purpose, e.g. no (RxD and TxD are crossed). CDB 410 or CDM 410 Connection Module: Set the switch S 5 (CDB 410) respectively S 7 (CDM 410) to position "RS232->AUX". or If a non-sick connection module is used: Connect the PC as shown in Fig. 5-2, Page Switch on the PC and power supply to the SICK connection module. 4. Set the communication parameters for the PC and the CLV. (See Chapter Starting "CLV Setup", Page 10-8.) 2. Connecting the PC to the optional programming adapter no The programming adapter can be inserted in the connection line between the CLV and the CDB 410 or CDM 410 connection module. The power supply is provided by the connection module. The design of the adapter is shown in Fig The HOST/PROG switch either connects the host interface 2 (RS 232) of the CLV to the host (if wired in the connection module) or to the PC. The CLOCK push button switch triggers the reading pulse, if the sensor input (Sensor 1) has been configured for reading trigger source in the CLV (default setting: reflector polling). Three LEDs indicate the activity of the switching outputs Result 1 to Result 3. The programming adapter can also be operated independently of the connection module (requires external power supply 12 V DC on DC connection) /O079/ SICK AG Division Auto Ident Germany All rights reserved 5-7

An external pulse is not required for "Percentage Evaluation" and "Read Rate Evaluation" mode Connecting the "Sensor 2" switching input This input is used exclusively to teach in match code 1. The teach-in procedure is an alternative to entering the match code 1 on the keyboard via the CODE COMPARISION field on the DEVICE CONFIGURATION tab in CLV Setup. In order to teach in the match code, the input is connected briefly to the power supply via a switch. This can also take place in the CDB 410 or CDM 410 connection module. The characteristic data is identical to that for the "Sensor 1" input (Table 5-6, Page 5-10). Fig. 5-6 shows the connections of the switching input.

The connections and procedure for teaching in match code 1 are described in Chapter Triggering the teach-in match code 1 via the "Sensor 2" switching input, Page Connecting the "Result 1" to "Result 3" switching outputs The three switching outputs can be assigned different functions for outputting result statuses independently of each other. If the assigned event occurs during the reading procedure, the corresponding switching output becomes live at the end of the reading pulse for the selected pulse duration. The pulse length can be set for each output independently of each other. Fig. 5-7 shows an example of how the "Result 1" switching output can be connected.

Only the host interface 2 (RS 232) remains active. This is useful when the CLV is integrated in a SICK network (RS 485). The CLV need not to be disconnected from the network. You also can manually set the parameters to the default setting by presenting the profile bar code no. 11 (Host interface: Temporary Default setting ON) from the card no during a reading pulse. Use the profile bar codes no. 12 (Host interface: Temporary Default setting OFF) to reset the CLV to the current parameters. 6-2 SICK AG Division Auto Ident Germany All rights reserved /O079/

57 Chapter 6 Operation 6.3 Quick start A PC need not be connected when the CLV is operated with the factory default settings. All bar code types are the default code types enabled except Pharmacode Starting up the line/raster scanner with the factory default settings 1. Connect the CLV to the SICK CDB 410 or CDM 410 connection module. 2. Switch on the power supply to the CDB 410 or CDM 410. Once the CLV has started, it outputs a tone to indicate that the self-test was successfully completed. Shortly afterwards, it outputs two tones to indicate that it has assumed reading mode. The "Device Ready" LED lights up. The "Result 1" ("Device Ready") output switches. 3. Align the CLV to the provided white polling reflector (special code) with a reading distance of approx. 300 mm (11.82 in) (not for CLV 414). 4. Start the reading pulse: block the polling reflector, e. g. with a sheet of paper. The "Laser On" LED lights up. The CLV switches the laser diode on and the red scan line appears. 5. Present the bar code pattern from Fig. 6-1 to the CLV at the reading distance specified in Table Align the bar code in such a way that the red scan line(s) is (are) almost at a 90 angle to the bars. 7. End the reading pulse: unblock the polling reflector. The "Laser On" LED is extinguished. The CLV switches off the laser diode. The CLV confirms that the bar code was read successfully by outputting a tone via the beeper. The "Result" LED lights up until the end of the next reading pulse. The "Result 2" switching output (Good Read) becomes live for the duration of 100 ms. The CLV can now be operated with the factory default settings. The device can be switched off without the configuration data being lost as no changes have been made to the parameter set.

The factory default settings or an application-specific parameter set of the CLV are in effect before changes are made. The CLV supports four different configuration methods: Configuration via the "CLV Setup" program and the CLV Assistant (parameter values are set via the serial interface). Configuration via AutoSetup (reading and code configurations for a bar code are adapted automatically via the optical interface (reading window)), see Chapter Configuring the CLV with AutoSetup, Page Configuration via profile bar codes (parameter values are set via the optical interface (reading window)), see Chapter 10.4 Configuring the CLV with profile bar codes, Page Configuration via command strings (parameter values are set via the serial interface), see Chapter 10.5 Configuring the CLV with command strings, Page Configuring CLV with the user interface of CLV Setup To be able to use "CLV Setup", a PC has to be connected and the program installed on it. The procedure for connecting the PC to the CLV is described in Chapter Connecting the PC to the host interface 2 (RS 232), Page 5-7. Installation and startup of "CLV Setup" and operation of the user interface are described in the appendix. See Chapter 10.3 Installation and operating instructions for the PC-based "CLV Setup" program, Page Transferring parameter sets between CLV Setup and the CLV Upload When the CLV 41x is being parameterized, CLV Setup runs in the offline mode. To be able to modify the current parameter set of the CLV 41x, this first has to be loaded to CLV Setup from the CLV 41x. This procedure is referred to as an upload ("Upload from CLV 41x" in the CLV 41x menu or [F3] key) during which CLV Setup always loads a complete copy of the current CLV 41x parameter set. This parameter set remains unchanged until it is overwritten by CLV Setup. With the help of the context menu (right mouse button), only the parameter just edited can be loaded ("Upload parameter") or from version 3.6 all parameters of one tab or one dialog box ("Upload parameters of this view") from the CLV 41x s memory (RAM). Download Changes made to the current parameter set in CLV Setup do not take effect until the parameter set has been transferred to the CLV 41x. CLV Setup always sends a copy of the complete parameter set to the CLV 41x, i. e. all of the existing parameter values in the CLV 41x are overwritten. The procedure for transferring and saving the parameter values in the CLV 41x is referred to as a download ("Download to CLV 41x" in the CLV 41x menu or [F4] key). With the help of the context menu (right mouse button), only the parameter just edited ("Download parameter") or from version 3.6 all parameters of one tab or one dialog box ("Download parameters of this view") will be temporarily loaded into the CLV 41x s memory 6-4 SICK AG Division Auto Ident Germany All rights reserved /O079/

59 Chapter 6 Operation (RAM). To finish the parametrization done by this way all parameters must be download again to the CLV with the "Permanent" option. Loading complete parameter set from the CLV (upload) Click in the toolbar or press [F3] key. CLV Setup loads the current CLV parameter set from the RAM of the CLV to its database and displays the values on the tabs. The "Device Ready" LED is extinguished during the upload. If the "CLV Setup" program does not recognize the parameters transferred during the upload, it outputs a warning. Unknown parameters can be edited on the EXTRAS tab by following the conventions for command strings. When the parameter set is saved, these parameters are also taken into account. Transferring the complete parameter set to the CLV and saving it (download) 1. Click in the toolbar or press [F4] key. The "Device Ready" LED is extinguished. CLV Setup copies the parameter set to the RAM of the CLV. The DOWNLOAD PARAMETERS dialog window with the save options is then displayed. PERMANENT: CLV Setup copies the parameter set to the RAM and to the EEPROM of the CLV. TEMPORARY: CLV Setup copies the parameter set to the RAM only. The changes are lost when the CLV power supply is switched off. 2. Confirm the dialog box with the desired save option. The "Device Ready" LED lights up again. The new parameter set is saved in the CLV, permanentely or temporarily dependent on the selected option. Saving the parameter set in CLV Setup 1. To save the modified parameter set as a new configuration file in CLV Setup, or to overwrite an existing file, choose FILE and SAVE AS. The SAVE AS dialog window is then displayed. 2. Enter the file name in the dialog window (file extension "*.scl") and confirm the entry. The new parameter set is now saved in CLV Setup in the subdirectory "data Function of tabs in CLV Setup (overview) Reading Configuration This tab (and additional dialog windows) are used to set the following: Scanning frequency Min. module width Min. reading distance Quiet zone Limitation of the evaluation range of the scan line Device Configuration This tab (and additional dialog windows) are used to set the following: Device number Source of the reading pulse /O079/ SICK AG Division Auto Ident Germany All rights reserved 6-5

65 Chapter 6 Operation Configuring the CLV with AutoSetup AutoSetup enables the reading and code configurations of the CLV to be adapted automatically to the application at hand. The following conditions must be fulfilled with regard to this: one bar code (code type, code length) fixed reading distance conveyor belt off (static reading) The CLV determines the code type, code length and the most favorable scanning rate for the bar code presented in the maximum reading distance of the application. This takes place in Free Running mode. Once AutoSetup has been completed successfully, the CLV copies the parameter values determined to its parameter set. All other code types and code lengths are then disabled. If AutoSetup was not completed successfully, the parameter set is not changed. The CLV does not read a Pharmacode or any EAN/UPC types in AutoSetup. It does not respond to an external reading pulse. AutoSetup can be activated in three different ways in the CLV: via the user interface of CLV Setup by presenting profile bar code no. 10 (on the card supplied no ) to the optical interface (reading window). See Chapter Activating AutoSetup with a profile bar code, Page via a command string (via the serial interface). See Chapter 10.5 Configuring the CLV with command strings, Page While AutoSetup is running, the CLV does not output any read result. Once AutoSetup has been completed, no error messages are output for diagnosed malfunctions in the event of a no read. Connecting a PC and using CLV Setup allows you to check the reading quality of the taught-in bar code in the Percentage Evaluation mode. Explanation AutoSetup procedure 1. Starting at 800 Hz, the CLV decreases its scanning frequency to 200 Hz in steps of 100 Hz. It evaluates the reading quality of 100 scans for each step. 2. The CLV performs verification reads +/ 50 Hz around the scanning frequency with the highest reading quality. 3. It then copies the optimum scanning frequency, the code type and code length to its parameter set. Activating AutoSetup via the user interface of CLV Setup In CLV Setup, AutoSetup can be started via the View menu, via the terminal emulator or as an executable device function (interactively). Preparing AutoSetup: 1. Switch on the power supply of the CDB 410 or CDM 410 connection module (of the CLV). After the CLV has started, it outputs a tone to indicate that the self-test was successful. After a short while, it outputs two consecutive tones to indicate that it has switched to reading mode. The "Device Ready" LED lights up. 2. Upload the current parameter set from the CLV with CLV Setup (the parameter set initially contains the factory default settings). CLV Setup displays the current values on the tabs /O079/ SICK AG Division Auto Ident Germany All rights reserved 6-11

66 Chapter 6 Operation 3. AutoSetup overwrites important values in the current parameter set of the CLV. Save the existing parameter set as a configuration file "*.scl" in CLV Setup before you change the parameter settings. See Chapter Configuring CLV with the user interface of CLV Setup, Page 6-4. Performing AutoSetup: 1. Click in the toolbar. The terminal emulator is launched. The CLV is in reading mode. 2. Present the application-specific bar code to the CLV at the maximum reading distance for the application. Note the limits of the CLV here. See reading field diagrams in Chapter 10.2 Specification diagrams, Page To prevent surface reflections, rotate the bar code towards the CLV approximately 15 away from the vertical axis. See Fig. 4-7, Page Click AUTO SETUP under DEVICE MODE. The CLV cancels reading mode. The "Device Ready" LED is extinguished. The CLV then starts AutoSetup. The red scan line appears when the "Laser On" LED lights up. 4. The CLV confirms that AutoSetup has been completed successfully by outputting two consecutive tones via the beeper and briefly activating the "Result" LED. To begin with, it only overwrites the appropriate parameter values in the RAM. The CLV returns to reading mode. The "Device Ready" LED lights up. The CLV only evaluates the presented code type and length the next time a bar code is read. 5. Perform an upload from the CLV. This is done by clicking in the toolbar. CLV loads the current parameter set from the RAM of the CLV and displays the new values in the tabs. 6. Perform a download to the CLV. This is done by clicking in the toolbar. The DOWNLOAD PARAMETER dialog box is displayed. 7. Confirm the dialog box by selecting the PERMANENT save option. The CLV saves the changes made to the parameter set permanently in the EEPROM. 8. Close the terminal emulator. Note AutoSetup canceled by the CLV in the event of a no read: If the CLV was not able to execute AutoSetup successfully after approx. 35 s, it cancels the search mode after the last decrease made to the parameter values by outputting three consecutive tones via the beeper. Then the CLV starts AutoSetup again with each wrong read. Close the terminal emulator and open it again. The CLV returns to reading mode. The "Device Ready" LED lights up. The current parameter set in the CLV does not change. If AutoSetup has been interactively started via DEVICE FUNCTION, the CLV automatically cancels the procedure after a few seconds. Terminating AutoSetup prematurely: To abort AutoSetup when once started via the terminal emulator proceed as describe above SICK AG Division Auto Ident Germany All rights reserved /O079/

67 Chapter 6 Operation Running AutoSetup again: 1. Click READING MODE under DEVICE MODE. The CLV switches to reading mode. 2. Click AUTO SETUP under DEVICE MODE again. The CLV then starts AutoSetup. 3. If AutoSetup is unsuccessful again, check whether the CLV is able to read the bar code correctly (reading distance, tilt, more than one bar code in the reading field). Checking parameter values stored in the CLV (after parameters are saved): 1. Switch the power supply of the connection module (of the CLV) off and on again. 2. Perform an upload from the CLV. This is done by clicking in the toolbar. 3. Check the values in the READING CONFIGURATION and CODE CONFIGURATION tabs. Only one code type may be active on the CODE CONFIGURATION tab. Note The CLV does not enter a real value in the parameter set for the parameters "Minimum Bar Width" and "Minimum Reading Distance, as it is not able to determine any absolute dimensions. This is why the value displayed on the READING CONFIGURATION tab does not match the actual conditions. Checking the stored read and code configurations: Once AutoSetup has been completed successfully, check the CLV settings as follows: 1. Click in the toolbar. The Terminal Emulator is launched. The CLV is in reading mode. 2. Click PERCENT EVALUATION under DEVICE MODE. The dialog box for the distance configuration is then displayed. 3. Confirm the dialog box with "OK". The CLV starts the percentage evaluation and displays the reading quality of each set of 100 scans continuously. See Chapter Percentage evaluation, Page Present the application-specific bar code at the distance taught in (at the minimum and maximum reading distance if the bar code in the application is in a variable reading range). 5. Check the reading quality in the terminal emulator. This should be between 70 and 100 % /O079/ SICK AG Division Auto Ident Germany All rights reserved 6-13

See Chapter Triggering the teach-in match code 1 via the "Sensor 2" switching input, Page For monitoring purposes/correcting faults Displaying and editing operating data Self-test Reading mode (standard operating mode) The CLV performs a self-test after it has been switched on. It is then set to the reading mode and confirms this by outputting two consecutive tones via the beeper. In the default setting, the reflector polling is the trigger source of the internal reading interval. The reading result is output by the CLV at the end of the reading interval via both host interfaces. Depending on the configuration, the switching outputs "Result 1" to "Result 3" become live for the predefined pulse length when defined events occur during the reading process (e. g. Good Read). The reading result of the host interface 2 (RS 232) can be displayed in the CLV Setup terminal emulator. The structure of the represented reading result correspondents to the data output format defined on the DATA STRINGS tab. The READING MODE can be called up by choosing VIEW in the menu bar or via the terminal emulator. Displaying the reading result in the terminal emulator: 1. Click in the toolbar. The TERMINAL EMULATOR dialog box is then displayed. 2. Click READING MODE under DEVICE MODE. 3. Align the CLV to the provided white polling reflector (special code) with a reading distance of approx. 300 mm (11.82 in) (not for CLV 414). 4. Start the reading pulse: block the polling reflector, e. g. with a sheet of paper. The "Laser On" LED lights up. The CLV switches the laser diode on and the red scan line appears SICK AG Division Auto Ident Germany All rights reserved /O079/

69 Chapter 6 Operation 5. Present the bar code pattern from Fig. 6-1, Page 6-3 to the CLV at the reading distance specified in Table 6-2, Page End the reading pulse: unblock the polling reflector. The "Laser On" LED is extinguished. The CLV switches off the laser diode. The CLV outputs a tone via the beeper to indicate that the reading result is displayed in the window of the Terminal Emulator. The "Result" LED lights up until the end of the next reading pulse. Note Fig. 6-2 shows two examples of reading result output: "good read" and "no read". The reading result comprises the data contents of the bar code(s) and the reading diagnosis data/constants parameterized to be output. In the default setting, the "Header", "Separator" und "Terminator" blocks do not contain any reading diagnosis data or constants. The CLV only reads and outputs here one bar code. The reading result for Good Read only comprises the data content of the bar code, the reading result for No Read comprises the parameterized wrong read format. Chapter Percentage evaluation, Page 6-17 explains the structure and function of a part of the reading diagnosis data. The CLV only outputs several bar codes in the reading result if the parameterized minimum and maximum number of bar codes is > 1, and several bar codes have been presented. The number of bar codes to be read/output for each reading interval can be selected on the CODE CONFIGURATION tab in the NUMBER OF CODES group. with: UVWXYZ = NOREAD = Good Read: data content of bar code No Read: wrong read format Fig. 6-2: CLV Setup: Reading mode: output of the reading result in the terminal emulator Note In the reading mode, the CLV does not output the contents of the polling reflector /O079/ SICK AG Division Auto Ident Germany All rights reserved 6-15

70 Chapter 6 Operation Tip The structure of the data output string can be configured via the DATA STRINGS tab: Up to 10 elements, consisting of constants (control characters, letters, digits) and/or reading diagnosis data, can be entered in the "Header", "Separator" und "Terminator" blocks. The position of the "Separator" block can be choosen before or after the code. 1. Select the DATA STRINGS tab. 2. Click in the HEADER input field. The dialog window EDIT PARAMETER: TFH is displayed. 3. Click the desired constants or placeholders for the reading diagnosis data. The selected elements appear in the text box at the top of the dialog window in the sequence in which they were selected. 4. Confirm the dialog box with "OK". 5. Repeat this procedure for the "Separator" and "Terminator" blocks. 6. Perform a download to the CLV. This is done by clicking in the toolbar. The DOWNLOAD PARAMETER dialog box is displayed. 7. Confirm the dialog box by selecting the PERMANENT save option. The CLV outputs the selected elements in the data output string of the host interface with the next reading result. Triggering the reading pulse via the terminal emulator: In the default setting, the reflector polling is the trigger source of the reading pulse. For test purposes the reading pulse can also be triggered directly via the terminal emulator of CLV Setup. To do so, a different trigger source must be selected temporarily in the CLV. 1. Choose the DEVICE CONFIGURATION tab. 2. Click the READING TRIGGER PARAMETERS button. The READING TRIGGER PARAMETERS dialog box is then displayed. 3. Click SERIAL INTERFACE under READING TRIGGER SOURCE. 4. Confirm the dialog box with "OK". 5. Perform a download to the CLV. To do so, click the SERIAL INTERFACE option again with the right mouse button and choose DOWNLOAD PARAMETER in the context menu. CLV Setup copies the parameter to the CLV temporarily. The serial interface has been activated as the trigger source of the reading pulse and is ready to receive appropriate commands (until the CLV is switched off). 6. Click in the toolbar. The TERMINAL EMULATOR dialog box is then displayed. The CLV is in reading mode. 7. Click the SW-TRIGGER ON button or press [F7] key. CLV Setup sends a start command to the CLV. The "Laser On" LED lights up. The red scan line then appears. 8. Present the bar code sample from Fig. 6-1, Page Click the SW-TRIGGER OFF button or press [F8] key. CLV Setup sends a stop command to the CLV. The "Laser On" LED is extinguished. The CLV switches off the laser diode. The CLV outputs a tone via the beeper to indicate that the reading result is displayed in the terminal emulator. The "Result" LED lights up until the end of the next reading pulse SICK AG Division Auto Ident Germany All rights reserved /O079/

71 Chapter 6 Operation Percentage evaluation In the Percentage evaluation mode, the reading quality of bar codes which enter the reading field of the CLV and are not moved (conveyor off) is assessed. This mode allows to check the correct alignment of the CLV to the bar code. The CLV performs 100 scans in "Free Running" mode and evaluates the reading quality. It outputs the reading result continuously every 2 s together with a fixed set of reading diagnosis data. The reading results can be displayed in the terminal emulator of CLV Setup. The switching outputs "Result 1" to "Result 3" and the beeper do not become live in the Percentage evaluation mode. The Percentage evaluation mode can be called up by choosing VIEW in the menu bar or via the terminal emulator. 1. Click in the toolbar. The terminal emulator window is then displayed. The CLV is in reading mode. 2. Click PERCENT EVALUATION under DEVICE MODE. The "Device Ready" LED is extinguished. The CLV initiates the percentage evaluation and outputs the reading results continuously. An example is shown in Fig Present the bar code pattern from Fig. 6-1, Page 6-3 and monitor the reading results in the terminal emulator window. The behavior of the "Result" LED also indicates the reading quality: LED is extinguished if reading quality is < 30 % LED flashes twice per second if the reading quality is 30 % to 70 % LED flashes five times per second if the reading quality is 70 % to 90 % LED is lit continuously if the reading quality is > 90 % Fig. 6-3: CLV Setup: Percentage evaluation mode: output of the reading result in the terminal emulator Fig. 6-4, Page 6-18 explains the structure and function of the reading diagnosis data for Good Read, and Fig. 6-5, Page 6-18 for No Read /O079/ SICK AG Division Auto Ident Germany All rights reserved 6-17

In Reading mode the CLV outputs the ST reading error status in the "Separator" block of the reading result (if the error status has been enabled via the DATA STRINGS tab. Disabled in default setting). ST= 3 indicates a device fault. For further values of the ST error status see Table 8-1, Page Switching off the CLV 1. If the parameter set was modified in CLV Setup or was only stored temporarily in CLV 41x via a download ("Temporary" option or via context menu (right mouse button)), the parameter set must be stored permanently in the CLV 41x by choosing the PERMANENT storage option. 2. Save parameter set as a "*.scl" configuration file in CLV Setup. 3. Switch off the power supply of the CDB 410 or CDM 410 or pull the plug of the CLV from the connection module. The last parameter set stored permanently in the CLV remains valid. We recommend that you print out the configuration file in order to archive the parameter set. 1. Click in the toolbar. The PRINT FILE dialog box is then displayed. 2. Enter a comment in the input field in order to assign the printout to the CLV. Confirm the dialog box with "OK". The PRINT dialog box for configuring the printer is then displayed. 3. Edit the dialog box accordingly and confirm.

77 Chapter 7 Maintenance 7 Maintenance 7.1 Cleaning during operation To ensure optimum reading performance, the reading window of the CLV must be clean at all times. For this reason, we recommend that you check the reading window at regular intervals, particularly if the device is operated under extreme conditions (dust, abrasion, humidity, finger prints). Laser radiation can seriously damage your eyesight The CLV uses a class 2 red-light laser. Looking directly at the laser beam can seriously damage the retina in your eyes. As with sunlight, never look directly into the laser beam. Switch off the device while it is being cleaned. Never look directly into the reading window while the device is in operation. Damage to the reading window The reading window is made of glass. Scratches and streaks on the window will reduce the reading performance. Use a mild, non-scouring detergent. Never use scratching or scouring motions to clean the reading window. Cleaning reading window Clean the reading window at regular intervals with a mild, non-scouring detergent, e.g. an antistatic glass cleaning fluid. Fig. 7-1 shows the areas that require cleaning. Use a soft, lint-free cloth. If necessary, clean the LEDs on the rear of the device. Line/Raster scanner Line/Raster scanner with 105 angle attachment clean here: Fig. 7-1: Cleaning the reading window Note Don t open the device. The producer warranty will be forfeited if the device is opened /O079/ SICK AG Division Auto Ident Germany All rights reserved 7-1

78 Chapter 7 Maintenance Cleaning other optical surfaces: If an external reading pulse generator with a sensor (e.g. photoelectric reflex switch) is used, make sure to clean the relevant optical surfaces (Fig. 7-2). Contamination on these surfaces can cause switching errors. If the reading pulse is generated by reflector polling, make sure to clean the surface of the reflector. clean here: Fig. 7-2: Cleaning the external optical sensor (reading pulse generator) 7.2 Maintenance The CLV does not require any maintenance except the described cleaning measures. Its self-monitoring function ensures fault-free operation over long periods of time. The CLV outputs detected device faults by sending the error status ST= 3 via the host interface (if the error status has been enabled via the DATA STRINGS tab. Disabled in default setting). See also Chapter 8.4 Troubleshooting, Page Disposal Irreparable devices or devices that are no longer required are to be disposed of in an environmentally-friendly manner: 1. Always observe the applicable national waste disposal regulations. 2. Remove the CLV housing. 3. Remove the electronic modules and the connection cable. 4. Remove the glass panel from the reading window and send it to be recycled. 5. Send the chassis and cover (zinc die-cast) to be recycled. 6. Send the electronic modules and connection cable for disposal as special waste. At present, SICK AG does not accept any unusable or irreparable devices. 7-2 SICK AG Division Auto Ident Germany All rights reserved /O079/

79 Chapter 8 Troubleshooting 8 Troubleshooting 8.1 Overview of errors and malfunctions which could occur Installation errors CLV aligned incorrectly with the object carrying the bar code (e.g. masking) Polling reflector or reading pulse sensor positioned incorrectly Electrical connection errors Interfaces on the CLV connected incorrectly (wiring error in CDB 410 or CDM 410) Parameterization errors Functions not adjusted to local conditions, e.g. communication parameters on the host interface are set incorrectly Technical limits of the device exceeded, e.g. relationship between the scanning frequency and the reading distance Malfunctions during operation Laser timeout for laser diode elapsed Device error (hardware/software) 8.2 Monitoring errors and malfunctions The CLV is self-monitoring: After the power supply has been switched on, the CLV automatically carries out a selftest, in which it checks important hardware components, before it is initialized (loading of parameter set and initializing of device functions). The self-test can be repeated at any time by canceling reading mode. For calling up, see Chapter Self-test, Page If the CLV detects an error during the self-test or at any other time, it outputs the error status ST= 3 via the host interface. Prerequisite: the error status is enabled for transmission. By default, transfer is blocked. While it is in operation, the CLV constantly monitors the laser diode and speed of the polygon mirror wheel. In addition, a watchdog circuit responds to error statuses. A timer automatically deactivates the laser diode 10 minutes (default setting) after a continuous reading pulse is initiated in reading mode with switching input pulse modes "Sensor Input" and "Serial Interface". In this case, the CLV outputs outputs three consecutive tones via the beeper. The reading pulse must be terminated by resetting the pulse signal. The laser diode is activated again by the next reading pulse /O079/ SICK AG Division Auto Ident Germany All rights reserved 8-1

80 Chapter 8 Troubleshooting 8.3 Error messages The CLV does not output any error messages except the ST error status. Value Meaning Possible cause Remedy 0 "Good read" not applicable 1 Incorrect check digit The check digit calculated by the CLV during the reading process does not match that printed in the bar code. 2 No bar code of the enabled code type found according to the evaluation criteria No bar code in the CLV's reading range during the reading pulse. Code type/length in the CLV not enabled for decoding. Reading window obstructed/dirty. Check whether the check digits in the bar code which were generated by the print process are correct. Synchronize the pulse of the CLV with the entry of a bar code into the reading area. Correct the code configuration parameters. Check the reading window. 3 Device fault Device fault Call up the self-test! See Chapter Self-test, Page If result 15000: Contact the SICK Service department. 5 Required number of successful multiple reads for the bar code not reached 6 Master: Number of slave reading results does not match the parameterized number of slaves 9 The OUTPUT FILTER function is also activated for the code comparison. The CLV has detected valid bar codes. However, these do not match the active match code(s) A D The CHECK MAX. NUMBER OF CODES function is active. The number of valid bar codes detected by the CLV in reading mode exceeds that specified under NUMBER OF CODES: MAXIMUM. It repeatedly outputs the defined error string until the number specified under NUMBER OF CODES: MINIMUM is reached. The "Code 32" evaluation option is activated for Code 39. The CLV is attempting to interpret 6-digit C39 bar codes as C32 bar codes (output as 9-digit decimal values). Table 8-1: Meaning of the ST error status in the reading result Conveyor speed of the object is too high. Scanning frequency is too low. Ladder-type arrangement for bar code relative to the conveyor direction: code height (bar length) too poor. Print quality too poor. The parameterized number of slaves does not match the actual number of slaves available. Timeout for the master is selected too short. Data connection between slaves and/ or the master has been interrupted. The scanned object does not have a bar code that matches the specified match code. One object in a set of objects with a constant number of bar codes, for example, contains more bar codes than defined in the application. The read 6-digit bar code is not a C32 bar code. The CLV outputs the defined error string instead. Check the conveyor speed. Adjust the scanning frequency. Check the code height. Check the print quality. Check the entered number of slaves. Check the master timeout setting. Check the cables between the slaves and the master. not applicable This message is used to indicate errors on the objects (e.g. check whether objects are homogeneous: mix with incorrect objects). not applicable 8-2 SICK AG Division Auto Ident Germany All rights reserved /O079/

After downloading the software, select OPEN in the dialog box to start the software. The software is installed in the sub directory Help of the main directory CLV. CLV Help will also be entried in the Windows start menu under Programs\CLV Setup. Restart the PC. Some Windows DLL files are possibly updated. The CLV Setup program, the CLV Assistant and the online CLV Setup Help are installed and ready. The program logs all of the files that are installed to the install.log file. This list is used by the uninstaller to remove CLV Setup and must not be deleted if you want to use the uninstaller at some time in the future. Updating program There are two options for installing a new version of CLV Setup: You can install the new version and still keep the old version (parallel installation) or You can install the new version over the old version (overwrite) 10-6 SICK AG Division Auto Ident Germany All rights reserved /O079/

97 Chapter 10 Appendix Installing new version and retaining old version If you want to install the new version and still keep the old version of CLV Setup, follow the procedure described under Initial installation. When the program asks you for the target directory, you must specify a new directory. Both versions of the software are then available but may not be started simultaneously. The configuration files "*.scl" of the old version can be used in the new version and contain the CLV parameter sets. In order to do so, copy the configuration files from the "data" directory of the old version to the "data" directory of the new version. Installing new version over old version When installing the new version over the old version, the files of the old version must first be deleted (exception: the "*.scl" configuration files). They contain the parameter sets of the CLV. The uninstaller of the old version removes the program files. You can use the uninstaller to remove all of the files (with the exception of the configuration files) or only selected files. The default setting is a complete uninstall (the configuration files are not deleted). With the custom uninstall, the files are listed and only selected files are uninstalled. If you choose this uninstall method, ensure that the main directory containing the configuration files "*.scl" is not deleted. We recommend that you move these files to a different directory and copy them back to the "data" directory later. 1. From the Windows Start menu, choose "Programs" and the uninstaller for CLV Setup. The uninstaller starts and guides you step by step through the uninstall procedure. 2. Select the uninstall method (complete or custom). 3. Install the new version of CLV Setup as described under Initial installation. Select the same directory. The new version of CLV Setup is installed. The configuration files of the old version can be used again /O079/ SICK AG Division Auto Ident Germany All rights reserved 10-7

98 Chapter 10 Appendix Starting "CLV Setup" The "CLV Setup" program is launched with the following default settings: Communication Transmit control character Receive control character Unit of measure Browser Language Company name User name Establish connection to CLV automatically Initial screen Storage confirmation prompt Last type selected File storage location COM 1; 9,600 bd; 8 data bits; 1 stop bit; no parity Start: STX, Stop: ETX Start: STX, Stop: ETX metric (depending on the selected installation) user dependent as selected for the installation as entered for the installation as entered for the installation at startup: yes on scanner selection: yes when the terminal emulator is started/closed: yes yes yes CLV 41x Table 10-2: Default settings of CLV Setup (extract) "data" (configuration files for CLV) 1. Switch on your PC and start Windows. 2. Select CLV SETUP from the Start menu. The SICK logo is then followed by the initial screen. 3. Confirm the initial screen with "OK". CLV Setup then checks whether a CLV is connected to the COM 1 port on the PC and whether the communication parameters on the PC match those on the CLV. If this is the case, the "Connected" status is displayed with the CLV specification in the bottom right corner of the screen, in the status bar. The detected CLV type is displayed in the toolbar in the DEVICE drop-down list (in this case: CLV 41x). The software then loads the internal device description of the CLV and the defaults settings of the parameters/parameter values from its database and displays these on the tabs. The software then copies the current parameter set from the memory (RAM) of the CLV. This is displayed on the tabs instead of the default settings. You can edit the current parameter set on the tabs. The default values are displayed when the device is used for the first time. Troubleshooting If CLV Setup cannot establish communication, it displays "No connection" in the status bar on the bottom, right-hand side. There are two possible causes for this. Either the CLV is not connected or the communication parameters on the CLV do not match those on the PC. In this case, CLV Setup enters the CLV type of the device it last communicated with in the DEVICE drop-down list on the toolbar. The default setting is CLV 41x the first time CLV Setup is started. The software then loads the internal device description for this type and the default settings of the parameters/parameter values from its database and displays these on the tabs SICK AG Division Auto Ident Germany All rights reserved /O079/

99 Chapter 10 Appendix 1. Connect the PC to the host interface 2 of the CLV using a 3-core RS 232 data cable (null modem cable)(cdb 410 or CDM 410: connect the PC to the internal, 9-pin "Aux" plug). See Chapter Connecting the PC to the host interface 2 (RS 232), Page Click (AutoBaud detect) in the toolbar or choose OPTIONS, AUTOBAUD DETECT. CLV Setup scans the serial interface by varying the communication parameters and sends a telegram to the CLV repeatedly. CLV Setup resets temporarily the communication parameters in the CLV 41x to the default setting and indicates the change by outputting a message. Fig. 10-5: CLV Setup: AutoBaud-Detect: Message about temporarily resetting the communcation parameters in the CLV 41x 3. Confirm the AUTO DETECT dialog window with "OK". As soon as a reply from the CLV is detected, CLV Setup conveys the values found for the communication parameters. Fig shows an example of the AUTOBAUD DETECT result display. CLV Setup displays "Connected" in the status bar on the bottom, righthand side. Fig. 10-6: CLV Setup: results of the AutoBaud detect function 4. Confirm the AUTO DETECT dialog window with "OK". CLV Setup displays the detected CLV type in a separate dialog box and asks you whether you want to upload the current parameter set from the CLV. 5. Confirm the dialog box with "Yes". CLV Setup then uploads the current parameter set from the RAM of the CLV to its database and displays the values on the tabs /O079/ SICK AG Division Auto Ident Germany All rights reserved 10-9

100 Chapter 10 Appendix You can edit the current parameter set on the tabs. or If the communication parameters are different to the default setting but known proceed as followed: 1. Select OPTIONS, then SERIAL INTERFACE from the menu bar. CLV Setup displays the current communication parameter settings of the PC in the COM PARAMETERS dialog box. 2. Ensure that the communication parameters of the PC and CLV are identical. Confirm the dialog box with "OK". CLV Setup attempts to communicate with the CLV again. If it is successful, CLV Setup displays "Connected " in the status bar on the bottom, righthand side. 3. Click in the toolbar. CLV Setup then copies the current parameter set from the RAM of the CLV to its database and displays the values on the tabs. You can edit the current parameter set on the tabs. Note Restoring the previous communication parameters If CLV Setup is to reset the communication parameters to the previous values on the next download, click the check box of RESET CLV 41X HOST INTERFACE in the download dialog box (Fig. 10-7). Fig. 10-7: CLV Setup: Restoring the previous communication parameters Note CLV in network operation (SICK Network RS 485) During communication between CLV Setup and CLV only the host interface 2 (RS 232) of the CLV is active (by default settings).
